The program removes case and function declaration errors ...
If it can be compiled, it is correct.

Tried your code, no problem
class TPart1
   {
   public:
void __fastcall Function_1( void)
{
const String Error_Str = "Error Of F1.";
throw (Error_Str );
}
};

   class TCombination
   {
   public:
TCombination( );
void __fastcall Act( void );
   };

   // *.h
   TPart1 *A_Part;

   TCombination::TCombination()
   {
A_Part = new TPart1( );
   }

   void __fastcall TCombination::Act( void)
   {
try
{
A_Part->Function_1( ); // After the program executes this sentence, it dies.
}
catch( ...)
{
ShowMessage( "Errors Found." );
}
}
int main(int argc, char* argv[])
{
TCombination c;
c.Act();
return 0;
}

There is a problem with my compiler. You can reinstall the system.
